Only the Jaguars receivers and linebackers have the same position coaches this year as they did last year. Coach Gus Bradley opted to retain Jerry Sullivan (receivers) and Mark Duffner (linebackers).

But for Paul Posluszny and Russell Allen, having Duffner run their meeting room doesn’t mean there won’t be a transition.

Bradley and defensive coordinator Bob Babich have their own playbook and their own teaching methods.

“I think it’s good we have the same coach because we know how to interact with him and we know what we’re going to get from him,” Posluszny said of Duffner. “As far as the technique that we’re going to be using on the field, there are going to be some big differences from last year. We have a lot to learn in a short period of time.”

During the off-season, it was up to Duffner to learn the Jaguars’ new system and then teach it to the linebackers when they arrived back at EverBank Field last week.

“Fortunately, there is some carry over,” Allen said. “Most of what we’re going to see [early on] is a change in terminology – doing the same kind of things but calling it differently. Over the course of the full installation, there is going to be a lot of change. It will be about communicating in the same language so we can be on the same page.”

When you start thinking about it...this defense has a lot of holes to fill. Not only do we need a pass rusher, but our entire defensive back field and line backer core need players. Even with a great draft, there is a limited amount of positions you can fill high quality prospects. We are definitely in for some growing pain in 2013.

When Daryl Smith was healthy he was a force in the middle. We missed him desperately last year. Last year just really sucked.
These new coaches have a huge job on their hands. Hope this GUS BUS has some decent tires on it.

They are going to be switching to a hybrid 3-4 sort of like what San Fran runs so I guess it will be a lot to learn in a short time especially when you still need two more linebackers... Bring back D.Smith!! Go Jags!
